WILLIAM A. ZIMMERMAN, IOF LOS ANGELES, CALIFORNIA, ASSIGNOR TO NATIONALCASH REGISTER COMPANY, OF JERSEY CITY, NEW JERSEY, A CORPORATION OF NEWJERSEY.

CASH-RE'GlSTER- SPECIFICATION forming part of Letters Patent No.739,530, dated September 22, 1903. Application filed March 10, 1902Serial No. 97.448. (No model) MAN,.a.citiz en of the UnitedStates,residing atLo's Angeles,'in"th county of Los Angeles and State ofCalifornia, have invented certain isters, of which Ideclare thefollowingto be a full clear, and exact description.

My invention relates to improvements in cash-registers, its object beingto provide means whereby when the same amount is registered successivelyit is necessary to press the amount or value keys only at the time ofthe first'registration.

In the-drawings, Figure l is a sectional view throughpart of acash-register, showing a bank of value-keys and myinvention appliedthereto. Fig. 2 is a'view of the special repeat-key thatI employ. Theinclosing tube is also shown in elevation in a separate view. Fig. 3shows the special detent-plate, with the repeat-key in operativeengagement therewith. Fig. 4 shows a top plan view of the repeat-keys II thought it unnecessary to'cornplicate the drawings byillustratiugtheindicating, registering, and other operative parts of thecashregister, as I. believe the invention can be fully'understoodwithout reference to those parts.

Referring now to the drawings, the numeral v 6 designates the fixed sideframe of the machine. The registering-segment 7, having-the yoke 8, ispivoted upon the central shaft 9,

but per se forms no. part of my present invention. The value-keys 10 arearranged preferably, though not necessarily, on the arc of a circle.Each key extends through and has a bearing in the key-framell, which issupported uponthe transverse shafts12,which' connect the side frames ofthe machine. Each key has a detent-pin 13 and a spring l4,wh'ich abutsat one end against the detent-pin and at the other against the innerledge of the key-frame and operates to retain the'keys-innormal outwardposition. llyin g ad jacent all type now on the market.

My invention may well be applied to a cash-:

of the keys and pivoted on the central shaft 9 is the regulardetent-plate' 15, which has a series of; hooks 16, one for each of thenine tent-pin passes under the inner point of the hook 16, whereupon thedetent-plate drops back to normal position, holding the key engaged. Ifnow another key be depressed, the detent-plate'willbe raised in the samemanner, releasing thepreviously-raised key andv engaging and holding thekey last pressed. Inthe usual manneryalso, if a key be-pressed and themachinepperated the detect-plate is struck by some operative part of themachine and raised, so as to automatically release the operated key.This is the modeof operation of most, if not 'all,,of the machines ofthis The general operation by which the detentplate is raised at eachoperation of the machine so as automatically to release any operatedkeyis fully set forth in the aforementioned'patent,.No. 610,492, andcomprises a rockin frame which is suitably j ournaledin the lower part;of the main frame 6 and is adapted to cooperate with an arm j, extend-.

ing downward from the -detent-plate15, and

this rocking frame. ,is'operated by the-move- 'ment of the drawer, sothat on the outward. movement of said drawer the rocking frame is notmoved;'but on the'closin'g o'f the drawer the rocking frameisrockedupward,so as to come in contact with the aforesaid arm j, and -therebylift thedetent-plateand-release the keys, allot which releasing movementis fully 'set forth and shown in the aforesaid patent.

It often happens, particularly at certain times and in certain places,that the clerk or other ,person operating the machine has' to registerthe sameamount successively. For example, in drug-stores at'rush timesthe to register successive sales he must each time press the. fivescentkey, because, as stated,

' peat-key? I ten 18-, .the outer tube-519, and ,the stem 20.;

the machine each time automatically rt ases the key last pressed.Theobject of my invention is to provide an arrangement whereby itshallbe optional with the clerk or person operating the machine whether thekey last pressed-shall be automatically released. To this end I providewhat I may callthe re- Th-is consists of the finger-but- The repeat-keymay have any suitable locajtion, but is preferably placed atthe top of"one of the series of amount or'value keys, as is shown in Fig. 1.Inlike manner with the l other keys thisspecial or repeat key hasiahearing iii-the supplemental frame 11. In like manner also it isprovided with the detent-pin .21, whi'chis secured in thetube'19 andextends laterally therefrom "The stem at its lower end and belowthelower 'end of the tube 1'9is likewise provided with a laterallocking-pin 22,- which lies in aplane preferably at right angles tothat. of. the dc tent-pin 21. Close beside the regular detent 1'5 andbetween it and the keys lies the special detent 23. (Shown in Fig. 4a.)This is. also pivoted upon'the central shaftz9 and is pro-Y vided withnine books 24, having incliiied faces 25, exactly like the hooks 16,withthe inclined faces 17. I The difference between the regulardetent-plate and the special de' tent plate consists in the fact thatthe latter has an extension 26, comprising a shoulder I Patent-*- 27, aninclined face 28, and a deep locking notch 29. It is evident that therepeat-key has two. motions-that is to say, it may be 'pressedin inthe'direction of its length or the shank maybeturned withinthe tube. If

" the repeat-key be pressed in, the special de-' ytent-plate is'therebyraised, so that the in-.f

of the paths of the detent-pins1 -3of the value-'- clined faces '25 ofthe hooks areentirelyout keys. .When in this, position,"thespecialdetent has no eifectwhateve-r on the; operation;

I f of the machine. The special vdetent-may be moved to" this positionby fully depressing the repeat-key, whereupon the pin 2l of therepeat-key becomes seated in thedeep. lockw ing-notch 29.- Ifnow' therepeat-key be givena turn-in the direction ofv the arrow, Fig. 4, thelocking-pin 22 will be moved under the shoulder 27, so as'to'lock thedeten't-plate'in" its'up'perposition andthe repeat-key in its 1 Ioperative position.

As previously stated,

'iwhenin- "this position the special detent-p'la'te hasno effectwhatever onjthe operation of the machine, and the regular operationofthe machine will automatically unlock the last-operated value-keysandpermit them to.v return to normal position. .60

If the I repeatkey, h owevef-, be in outward position, as

., shownin Fig. 1, then the hooks 24 are exactly coincident with thehooks 16 of the regular detent pl-ate. Under this construction'thelast-,cperated'valne-key is notreleased by the regular. fOPGiillilOll bfthe machine, but only "theis'pecial push-button;

by the pressing in of some other value-key. Of coursethe regulardetent-plate will still be operated in' its'regular manner; but thespecial detent-plate will'notbe moved by the operation of the machine,and hence will not release the last-operated key from depressed positionuntil the snbsequent'operation of another key, whereupon of course boththe detent-plates will be raised, thereby releasing thelast-operated'key." If the same amount were to be registeredsuccessively or if even the same value-key in any bank were to be usedsuccessively, with myimproved-device it would not be necessary torepressthat key in registering the successive sale, because, asstated,it will remain in operative or depressed positioniuntil released by thesubseton-and 'itwill readily be observed that when my invention isapplied to such a machine to registersnceessive sales of the same amountit is onlynecessary to turn the crack or press Havingthus-described myinvention, 1
